OS/390 REXX Program Development

This course introduces the REXX instructions used to define and vary program flow. You will learn how to share data between a calling host environment program and the REXX program that is called, or between a REXX program and a subroutine or function. The course covers REXX instructions that support terminal Input/Output (I/O) operations, and that read and write information from disk files. Learn about REXX facilities that receiving arguments and returning results, and REXX instructions that control data movement onto and off of a Program Stack. You will be able to develop a REXX program that accepts arguments on invocation.

REXX Program Development training covers such topics as:

Terminal Input/Output
REXX Flow Control
Passing and Receiving Arguments
Program Stack Structures
Simple Disk Input/Output
LINEIN and LINEOUT Functions

This course is designed for automation specialists, system and application programmers, and other individuals who want to become familiar with the REXX programming language

OS/390 REXX Program Development Everything OS/390

Description
This course introduces the REXX instructions used to define and vary program flow, the order in which program instructions execute. Flow control is examined by using keywords to vary the order of execution. Students will examine the ways data can be shared between a calling host environment program and the REXX program, which is called, or between a REXX program and a subroutine or function. REXX instructions that support terminal Input/Output (I/O) operations are discussed. REXX facilities for receiving arguments and returning results are analyzed. REXX instructions and interfaces used to read and write information from disk files are also examined. In addition, the Program Stack, buffers, and the use of REXX instructions to control data movement onto and off of a Program Stack are explored. Students will be able to develop a REXX program that accepts arguments on invocation. This course is written to OS/390 2.x.
Audience
This course is designed for automation specialists, system and application programmers, and other individuals who want to become familiar with the REXX programming language.
Prerequisites
The student should be familiar with the basics of computer logic operations and programming. Also required is familiarity with a text editor, and knowledge of one of the environments that supports REXX as a programming language. The student should be able to manipulate REXX variables and expressions, format character strings, and create expressions. The information can be obtained by taking the OS/390 REXX Programming Fundamentals course.
